A fiber-reinforced polyurea (FRPU) composite provides high load-carrying capacity and is applied by simply spraying it onto the member surface. Unlike existing reinforcement approaches, the FRPU coating method can prevent the ductility of concrete beams from deteriorating and the concrete surface from debonding.
If fibers are too long, uniform distribution of the fibers becomes difficult. Longer fibers can be used when larger aggregates are present to shear the bundles of fiber apart. Short fibers are used with small or lightweight aggregate. Polypropylene fibers tend to hold the concrete mix together.
This paper presents the experimental investigation carried out to study the behavior of polypropylene fiber reinforced concrete (PPFRC) under compression and flexure. Crimped polypropylene fibers and twisted polypropylene fiber were used with 0.0%, 0.2%, 0.4% and 0.6% volume fractions.

Jan 12, 2015 · “As is typical in the synthetic fiber business,” he says, “the answer to this question is a resounding….it depends! For microfibers, it depends on the type to some degree — for low-dose monofilaments, there should be little fiber evidence. Microfibrillated fibers can sometimes fuzz, depending on the level of polish.

In this study, ten large ultra-high-performance concrete (UHPC) beams reinforced with steel rebars were fabricated and tested. The experimental parameters included reinforcement ratio and steel fiber type. Two different reinforcement ratios (ρ= 0.94% and 1.50%) and steel fiber types (smooth and twisted steel fibers) were adopted.
Three dimensional secondary reinforcement replaces wire mesh for a better concrete at a lower cost. AFC and MCP fibers are easy to use. Any concrete admixture may be added to the concrete without any change due to the presence of the fibers. Polypropylene fibers are highly resistant to both acid and alkaline environments.
